We first saw this remarkable item at a living history museum. It really revolutionizes hand clothes washing, and is a big step up from the wash board especially for larger loads. This metal plunger with a wooden handle agitates your washing load. It works great in a wash tub, large bucket, bathtub, etc. A must have when your washing machine is out of commission for any length of time, and will come in handy any time for large items in your bath tub. One customer we sold to, finds it desirable over the laundry mat, for all her laundry needs. The Rapid Washer is made of tin-plated steel. Please note the Rapid Washers are made on the same machine as they were in the 1800s, and while they are made to be used, they may have some irregularities and a small amount of rust developing is normal. We don’t recommend the Rapid Washer for use in, or near, salt water.
